feat(unreal): consolidate map compression scripts

[dgibbs64]

Description

This pull request consolidates and improves the Unreal map compression modules in the project. It replaces the previous separate scripts for Unreal and Unreal 2 map compression with a unified and more robust script, updates the command definitions and options accordingly, and removes redundant code. The main benefits are easier maintenance, broader file type support, and improved user experience.

Module Consolidation and Improvements:

• Added a new unified compress_unreal_maps.sh script that compresses both Unreal and Unreal 2 maps, supports a wider range of file types, provides better output, and handles old compressed files more robustly.
• Removed the old compress_ut99_maps.sh and compress_unreal2_maps.sh scripts, as their functionality is now covered by the new unified script. [1] [2]
• Updated module fetching logic to remove references to the deleted scripts.

Command and Option Updates:

• Updated core_getopt.sh to define a single cmd_map_compressor_unreal command for all Unreal engines, replacing the previous separate commands for UT99 and Unreal 2. Also updated the logic that adds this command based on the engine type. [1] [2]

Other Improvements:

• Added a missing core_exit.sh call to the end of install_ut2k4_key.sh for consistent script termination.
• Disabled shellcheck warning SC2154 in .shellcheckrc to avoid false positives about undefined variables.

Fixes #3632
